packages/catalogue/src/region/water
A region's water and lava, from its features: a lake's sheet over its bed and the tile of shore round it, 1 m under the shore (the ground higher than it shows through, so the water is where the land is lower: the bed, deep, and the inner slope of the shore, shallow at its edge); a volcano's lava over the four tiles round its crater's middle, 2 m under its rim, a pool about 96 m across where the crater dips under it. The tiles a sheet spans are wet: no road is routed through them and nothing grows there. Pure and deterministic.
